Dentistry ExpertThis case involves an elderly female patient who had implants placed in her jaw. When the implants were placed, a gap was found in the manufactured gum and the dentist put acrylic in to fill the gap. During the first fitting, the posts got stuck and the dentist used a significant amount of force to release the implants. In the months following the implant placement, the patient found it difficult and painful to remove the dentures. About 7 months after the implants were placed, they fell out while the patient was eating. She bit into a sandwich and the implant came out, puncturing her upper lip. The dentist put in a temporary acrylic fix which deteriorated in weeks. The patient was subsequently limited to a soft food diet.

I have been in clinical practice for 30+ years and all of the disciplines involved in the treatment of this patient are within my expertise. As with any dental procedure, there are risks and benefits. Approximately 5% of implants fail, however, they can usually be replaced. Certain factors have an impact on the success of the implants including a smoking history, dental hygiene, and occlusion (bite). I have lectured on this topic.
